The continuous belt design is ideal for large quantities of similar work pieces being processed. Options include Class A models specifically designed for flammable solvents and a HEPA (High Efficiency Particulate Air) filtered model for applications that require Class 1000 cleanliness. These ovens provide extremely consistent and repeatable process results at temperatures up to 260°C (500°F).
Minneapolis, Minnesota, USA, May 21, 2020 – A manufacture of batteries is purchasing two Despatch Conveyor ovens for its automated production line. The ovens are needed to bond materials in the battery assembly inside a mold. The molds are inserted and removed from the conveyor oven with automated pick and place robots. Tight temperature control with very little variance is critical to the process to ensure proper bonding.
The size and performance of the Despatch PCC2-15 conveyor oven provided an ideal solution with only minor modifications needed. The conveyor belt was designed to accommodate up to 15 parts across the width and a load of up to 60 pounds per linear foot. Attachment links were added to interface with the customer’s fixtures. A Watlow EZ Zone controller with PID and custom sensors were added to allow communication with the automation system.
“This was a big win for ITW EAE and resulted from the excellent reputation of the Despatch brand and the relationships developed by our sales representatives,” states Mark Clementz, Despatch Sales Manager. “The company has plans to order as many as 40 more of these ovens to meet growing demand.”
Minneapolis, Minnesota, USA, January 30, 2020 – ITW EAE, a division of Illinois Tool Works announces they have redesigned the HEPA filtered Despatch PCC1-40 Conveyor Oven. The new design provides flexibility in a standard package that will reduce the time to ship to just 8 weeks. The newly designed PCC1-40 model comes standard with a HEPA filter for Class 1000 cleanliness but can also be ordered without. It has a stainless-steel interior and exterior with all interior seams continuously back welded to prevent migration of insulation particles from entering the oven work space and allow for easy washing of the chamber.
The Despatch PCC1-40 is designed with built-in flexibility. The conveyor opening has an adjustable slide gate that can be easily lowered to prevent heat loss and raised for larger parts. The entrance and exit length of the conveyor can be adjusted by shifting the conveyor. This shift does not change the overall length of the conveyor. The PCC1-40 can be ordered in an end-to-end configuration to provide an additional heating zone.
“Customer needs vary widely, and they often don’t have time to wait for a custom build,” states Jeff Bell, Despatch Product Manager. “We design our standard product offerings to meet the needs of the majority of our customers which drastically reduces lead time and ensures the highest quality.”
The PCC1-40 has a four cubic foot chamber (18" x 42" x 9") and a maximum operating temperature of 500°F. A stainless-steel perforated supply plenum provides an even distribution of vertical down airflow for superior temperature uniformity on all interior parts.
Minneapolis, Minnesota, USA, March 15, 2019 – A medical device manufacturer required an oven to preheat an aluminum mold for a silicone part that was to be filled and cured in the next manufacturing step. The company develops innovative products that improve patient outcomes by enabling minimally invasive surgery.
The oven was to be installed in an automated manufacturing cell and needed electrical interlocks and communication that were not included in the standard oven electrical package. Since the oven was to be placed in an automated cell, footprint and access to the oven would be limited.
Despatch visited the customer to work out a solution and was able to meet the customer’s requirements with minor modifications to the PCC1-40 conveyor oven.
The customer is now able to access the electrical panels and the oven interior for maintenance without compromise. The Despatch applications team also visited the site and exchanged 2D drawings and 3D models to ensure proper fit.
To meet the customer’s automation needs, Despatch engineers incorporated an AC belt drive and a temperature controller with a machine interface to allow the automation system to index belt motion and control temperature in the oven without human interaction. Multiple status relays were incorporated into the controls including oven power, conveyor running and an eye on the conveyor discharge, to provide feedback to the customer’s PLC. All these features along with the inherent high level of temperature control in the Despatch oven work together to assure flawless operation.

High volume recirculating fans maintain consistent, uniform temperatures required by MIL STD 883D while removing heat generated by the load. The PBC burn-in oven allows for traditional horizontal loading with side-to-side horizontal airflow providing exceptional temperature uniform across the load.
Minneapolis, Minnesota, USA, December 6, 2017 – Despatch has redesigned its RAD2-19 and RFD2-19 Cabinet Ovens to accommodate customer demands for a smaller footprint. The original design of these cabinet oven had the controls on the side of the oven. The new design has the controls on the bottom of the oven which significantly reduces the amount of floor space that the oven requires. The new design is has a width that is 20 inches less wide than the previous model.
“Having the controls up at eye level was a convenience in the old design but customers ensured us that saving space was more important to them,” said Jeff Bell, Director of Product Management at Despatch. “We tilted the Protocol 3 controller up towards the operator for easier access. And for customers who have more frequent interaction with the controls, we offer software which allows the oven to be controlled from a laptop computer.”
Despatch RAD2-19 cabinet oven has a 19.5 cubic foot chamber and a maximum temperature of 650°F. It features horizontal recirculating airflow to ensure exceptional temperature uniformity throughout the oven. The result is proven reliability in demanding production and laboratory applications, such as curing, drying, stress relieving, aging, and other process-critical applications. The RFD2-19 is a Class A model designed to meet NFPA 86 requirements for applications that include flammable solvents or large amounts of moisture removal.
Minneapolis, Minnesota, USA, June 1, 2017 – Despatch, is expanding its line of PTC top-loading ovens to include a new 48 cubic foot model. These ovens are specifically designed and used for burn-in, qualification testing and calibration of down-hole drilling instruments. With recent advances in technology and a wider range of processes, a larger oven is required which will accommodate larger tools and instrumentation.
While the PTC oven is designed to stand up to harsh oilfield conditions, it is also used for other applications that require a long narrow chamber. Customers have used the PTC oven for curing wire coatings in a continuous process configuration. Marinite end-caps can be machined to insert instruments, testing leads or tooling and can also be removed to allow two ovens to be used end-to-end for longer loads.
“After receiving an increase in requests for PTC top-loading ovens with a larger chamber, it became clear that industry requirements were changing,” said Tom Weller, Applications Engineer at Despatch. “We decided to make a standard 24 cubic foot model that can ship with a shorter lead time.”
The new 48 cubic foot PTC chamber is 24 inches high by 24 inches wide with a twelve-foot length. The oven can reach temperatures up to 500℉ (260℃) and features horizontal airflow with adjustable louvers to ensure uniform airflow across the entire length of the chamber. The top-loading oven allows heavy equipment to be loaded into the test chamber by crane and silicone door seals and positive-latching clamps hold the door securely in place.
Minneapolis, Minnesota, USA, May 25, 2017 – Despatch, a leading technology and equipment provider for the solar industry, is pleased to announce the U.S. Patent and Trademark Office (USPTO) has issued Patent No. US9589817B2 protecting the intellectual property of its DriTech™ Dryer. The dryer already has a large installation base with a proven performance track record.
“The DriTech™ Dryer introduces a unique hybrid heating technology that addresses industry challenges associated with faster belt speeds, increased paste VOC concentration and thinner wafers,” said Daniel Ruf, Engineering Manager at Despatch. “Customers are seeing improved cell performance and efficiency with this revolutionary technology.”
The DriTech™ dryer is designed to decouple the VOC removal and binder burn-off for a more efficient drying process. Dryers typically use either convective or IR drying, and rely strictly on a belt speed and temperature relationship. DriTech’s unique hybrid heating with Smart Tube™ technology provides multiple heat delivery mediums to efficiently and effectively remove solvent (VOC) from the paste while safely retaining the binder. A centrally located point-of-generation thermal oxidizer provides maintenance-free VOC abatement ensuring that the chamber remains free of contaminates. Air dilution, up to five times the dilution of conventional dryers, reduces the solvent concentration within the chamber and eliminates dead spots. Airflow is precisely managed to reduce cold air entrainment at the entrance and exit. A rapid peak temperature and internal management of the insulation surface temperature minimizes condensation.
Minneapolis, Minnesota, USA, March 30, 2017 – The U.S. Patent and Trademark Office has issue Patent No. 9,598,795 protecting Despatch Split-Zone™ Oxidation technology. This patent applies to the split zone control which provides two discrete thermal profiles for the upper and lower half of the chamber. Separate plug fans and controls allow you to increase the temperature in the upper half of the oven by as much as 10 ℃.
“Despatch invented center-to ends carbon fiber oxidation technology which has now become the industry standard,” said John Stafford, Carbon Fiber Business Development Manager at Despatch. “This next-generation Split Zone technology will allow customers to aggressively push the oxidation rate, reduce oxidation cycle time, and lower the cost of high quality oxidized fiber.”
Because each oven is now split into two zones, the number of ovens required to properly oxidize the fiber can potentially be reduced. This results in a needle-moving reduction of greater than 50% in annual cost of operation.
Minneapolis, Minnesota, USA, February 14, 2017 – A second customer evaluation of the Despatch Split-Zone™ Oxidation Oven was recently completed. The results confirm that the new oxidation technology provides a significant reduction in cycle time.
The customer, a large North American based carbon fiber producer, reported that they could have up to 20% higher speed and throughput using this system. Half of the increase is directly related to longer heated length and the rest attributed to the split zone and temperature uniformity compared to their existing production line.
An earlier customer test conducted using premium grade precursor achieved the target density in just two zones with a dwell time of 44 minutes, a reduction in cycle time of nearly 35%. A white paper is available on the Despatch website with complete details on this customer evaluation.
“The Split-Zone Oxidation Oven introduces revolutionary technology that allows customers to push the temperature in the oven beyond what was ever possible before,” said John Stafford, Carbon Fiber Business Development Manager at Despatch. “As customers become more confident in the technology we expect that cycle times will be reduced even more than these initial tests.”
Patent protection is pending for the Despatch Split-Zone™ Oxidation technology. This patent applies to the split zone control which provides two discrete thermal profiles for the upper and lower half of the chamber. Separate plug fans and controls allow you to increase the temperature in the upper half of the oven by as much as 10⁰C. An additional patent is pending for the orifice-plate nozzle structures which eliminate the side-to-side and directional variance inherent in conventional nozzle designs.
